with respect to the other longitudinal 1nztrgins.

The impressior. cylinder is denoted by 1 construction and no specific description An endless carr er 1O is provided at intervals with grippers 11* arranged to take the the ends of the gu desl7, 8 and 9, and convey the sheets to a point overethe dclivery-table, 12 where the grip pers areopened by a cam and its plate cyli iders by 2.

tr te sheet illustrated in. :Fig; .8 is' s iew as provided with t-wo"eonti nuous margins.

I 16, 17,.1engthwise of the travelof thesluaiat and lalso fire intermediateshorten"margins. g 18,. 1;9,-20, 2 1,;22, longthv'visefof the travel-of the sheet, arranged in staggered orderfinteiw med'iate theJs-ide' lllitlfgiflS, 16 17. i It f quently occurs in printingthnt mitlj i: i d

lengthwise of the travel, ofillhfifillflet arejnot :r

continuous from the head to the tail-lof the sheet and it is to provide rneaneforsim eess,

ting .the freshly I rinted face (at 'ithoinder 4 is provided with a aLlity 0 mar ginal risers which we adjustable both laterall and circumferentially' on the cylinder an which correspond in length and position to the margins on the sheets to be delivered, In the present instance the marginal risers 23, 24, are arranged to engage the continuous margins 16, 17, of the sheet illustrated, while the marginal risers 25, 26, 27, 28, 29 are arranged to engagv he shorter margins 18, 19, 20, 21, 22, resp; ctively, of the sheet; the sheet thus being supported lengthwise thereof by its continuous and staggered n'iargins as it passes around the cylinder 4.

The means which I have shown for bold ing the marginal risers in position around the surface of the cylinder includes clamping plates 30, engaging the risers, adjustable shoes 31, spirally arranged undercut grooves 32 in, the face of the cylinder and clamping screws 33 engaging the plates and shoes.

This arrangement, it will be seen, .will

. perinit the very rapid positioning of the sheet to brin it'into proximity to the head of the slip s eet for insuring the transfer of the-two" sheetsto the delivery carrier grippers 11. The delivery end of the movable guide '8 is arranged to be. immediately removed from its engagement with the freshly printed .face of the sheet as soon as the printed sheet and slip sheet areengaged by the grip ers 11, .so that the said freshly printed ace of the sheet will not be 'smutted by the dragging of the guide over said face. The means which I have shown for moving I this guide comprises a ca 1 34=on= the shaft 5 of-the' delivery cylinder, whichcam engages a'stud orv roller 35 fast to la bani-S5 connected to an arm37 fast to a r0 .kba'rf38',to which rock bar the movable gu dej '8 is also fixed.

This cami 34 may be a listed: toproperly' time the. movement of t e-guide 8 with respect to the grippers 11 (if the-delivery carrier.

- I" provi e. means for niaintaining 'control of the. sheets on the delivery. cy1inder after vthe heads-of the sheets arereleased by the grippers 6, said means in"the"pre sent .in-:

stance; comprising a' seri-es of iriction rollers 39 carried by spring-actuated pivotedflat 41 to armsl42- adjustable'laterally I desired amount of pressure which-these rollers39 exert 1.11 9 the. marginalrisers' isfad-- elorxgdJlie cross bar '43 and held in the desired adjustments by the setscrews}14. The

justed-. by meansjof springs .45; 1t is "to 'be' understood-that there may be one; of theserock levers .40-

1 ,eea'paa rollers 39 for each of the marginal risers also that these rollers may be prevented from pressin against the face of the.- cylinder when t e ride ofi the ends of the marginal risers. his latter result may be accomplished by suitable adjustable stops 46 carried by the arms 42 and arranged to be engaged by tailpieoes 4? on the rock levers 40. It is intended that these rollers 39 should coact with the marginal risers to maintain control of the printed sheets until the heads of the sheets are engaged by the delivery carrier grippers 11.

It isevident that the driving connections between the several parts may be arranged to drive the parts at the proper relative speeds-and assuch driving mechanism may be of any well known or approved form, no specific description of the same will be given herein.

It is also obvious that .when I refer tothe element 4 as a delivery cylinder, I wish to include by such term a reel or other equivalent means capable of passing the sheets ing presses including. a'de ivery ylinden l risers thereon for engaging the m'fig'in's'of the sheet whether continuous or staggered r for passing the sheet around the cylinder 'without smuttin'g'the freshly printediape of the sheet and means coa'cting. with the risers for controlling-the movement of the:,.she t.
